Why digital sovereignty matters with Shelly

Shelly is headquartered in BG and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Shelly runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

Shelly is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Shelly together with your other vendors and gives a total score, a heatmap and the main risk drivers.
